6657. 'That they also will join themselves to our enemies and fight against us' means that in that way allied forces who inflict harm will be made stronger. This is clear from the meaning of 'joining themselves to' as being made stronger, for when enemies are joined by a very large number they are made stronger; from the meaning of 'enemies' as allied forces who fight alongside one another; and from the meaning of 'fighting against us' as inflicting harm, for when a battle is fought against someone, harm is done to him to the extent that he cannot counteract it. The implications of all this are that surrounding every person in the world and also surrounding every good spirit there is a general sphere of endeavours from hell and a general sphere of endeavours from heaven. The sphere from hell is a sphere of endeavours to do harm and destroy, that from heaven is a sphere of endeavours to do good and to save, see 6477. These spheres are general ones, and there are likewise particular spheres surrounding every person, for there are spirits from hell present with him and there are angels from heaven, who are dealt with in 5846-5866, 5976-5993. By these spheres a person is kept in a state of equilibrium and has the freedom to think and will what is evil or to think and will what is good.

[2] When therefore a member of the Church enters into temptation, which happens when he is let into his own evil, conflict takes place around him between the spirits from hell and the angels from heaven, 3927, 4249, 5036; and the conflict lasts for as long as the person is kept in his own evil. Sometimes in that conflict it seems to the spirits from hell that they are going to win, in which case they surge up. At other times it seems to them that they are going to be beaten, in which case they fall back, fearing that more angels from heaven will join up against them and so they themselves will be cast down into hell, never to emerge again, which is exactly what happens when they have been beaten. These are the things that are meant by superior strength if they increase and by the statement that allied forces who inflict harm will be made stronger.

[3] Spirits from hell, when they fight against angels, are in the world of spirits, where they are in a state of freedom, 5852. From all this one may now see what is meant in the internal sense when it says that the children of Israel were molested and oppressed in such ways by the Egyptians, but that the more they were molested, the more they multiplied, and that Jehovah, who is the Lord, fought for them, kept the Egyptians in check by means of plagues, and at length drowned all the Egyptians in the Sea Suph.
